What issues need to pay attention to the purchase of waterproof products The current building materials market management is not standardized, there are many fake and inferior products on the market, should choose a relatively well-known brand at the time of purchase. The real environmental protection waterproof material shall have the test report, product test report and product certificate issued by the nationally recognized testing center.
In addition, pay attention to the manufacturer's service measures when purchasing waterproof coatings.

In fact, the most critical part of brush waterproofing is the base surface treatment and post-protection. The poor handling of the ground, like building castles in the air, is an empty talk. In the latter period of time, no protection is provided. Brushing is also equivalent to burying an eye-catching net. It does not play a role in waterproofing.
How to deal with grassroots?
Usually the base surface treatment should: 1. Carefully clean the base surface to remove floating dust, cement agglomerate and loosen the base layer; 2. Use a brush to sweep the dust on the base surface.
Waterproof layer construction should reach what standard?
The waterproof coating is full of paint, without any omissions. It is firmly bonded to the grass roots, free of bubbles, cracks, delamination, and smooth surface. The brushing height of the rolled up parts is basically uniform and uniform, and the thickness must meet the requirements of product regulations. After construction, construction of other follow-up projects shall be carried out after the time specified in the specification.

Toilets, kitchens, balconies, basements, floors, and walls of all rooms on the first floor are waterproof. Among them, the walls of toilets and baths are usually brushed at least 1.8 meters from the surface of the waterproof layer, or full to the top; the kitchen and balcony floor and wall, the first floor of the house and all the walls to do 0.3 meters from the ground Waterproof layer; the basement floor and all walls are waterproof. Wall grooves should also be waterproof. When pipelines, floor drains, etc. cross the floor, the waterproof layer around the holes must be carefully constructed. The buried water pipe in the wall shall be larger than the diameter of the pipe, and the groove shall be smooth and brushed with a waterproof coating.
Tip: If the original drainage and sewer pipes and floor drain locations are changed during the renovation, waterproof measures must be taken in the surrounding area.
Waterproof layer construction should be monitored when those key links?
First, waterproof parts should be comprehensive;
Second, waterproof layer construction must be strictly in accordance with the product manual brushing and brushing a certain thickness;
Third, the construction process should be detailed: the wall surface and the ground joints, Yin Yang angle, water pipes, floor drains and sanitary ware around the laying of the heat pipe and the nursery ditch is the key waterproof parts, construction must be careful.
Why do protective layers after waterproof construction?
After the waterproof layer is completed, it is necessary to continue to apply tiling on the surface. It is often very easy to cause damage to the waterproof layer. If it is not repaired or found in the damaged area, it will inevitably cause leakage in the future, so it is necessary to apply a protective layer. Usually used is the cement added interface agent stir brushing, this waterproof can be foolproof.
After waterproofing is done, why do you need to do a water shut-off test?
Closed water test can verify the waterproof layer waterproof function is normal. Close the water test to seal the entrance with the outlet, the highest aquifer depth of not less than 20 mm, storage time of not less than 24 hours, check for leaks.
Under what circumstances to do watering test?
For the acceptance of lightweight wall waterproof construction, a watering test should be taken. Even if the water pipe is sprayed on the wall of the waterproof paint continuously for 3 or 4 minutes from top to bottom, no penetration on the other side of the wall can be accepted.
